This paper presents a revised sighting survey plan for western North Pacific in 2019. The original plan was presented to the IWC SC in 2018, which included sub-area 6E to be covered by Yushin â€“maru No. 2 (YS2) and sub-areas 7WR and 7E to be covered by Kaiyo-maru No. 7 (KY7) in May-June 2019. The revised plan presents two differences regarding the original one: i) sub-areas 7WR and 7E will be covered in May-June by two vessels, Yushin-maru No. 1 (YS1) and Yushin-maru No. 3 (YS3), instead of one; ii) an additional survey will be carried out in sub-area 7WR from August to September 2019 by one vessel (KY7). The main objective of the surveys is to investigate the distribution and abundance of common minke whales in those sub-areas. The sighting protocols are the same in all surveys.
